Spring mattress



Patented Sept. 19, 1950 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to spring mattress and is directed' more particularly to mattresses for a double bed.

The novel features of the invention are directed to the provision of a mattress adapted to be occupied by two persons in a double bed.

According to novel features of the invention means is provided which interposes a barrier between the occupants of the bed so as to separate and keep them apart for their comfort.

The novel features of the invention include an arrangement of springs which while capable of performing the desired function does not detract from the appearance of a bed when made up.

All of the above objects I accomplish by means of such structure and relative arrangement of parts thereof, as will fully appear by a perusal of the description below and by various specific features which will be hereinafter set forth.

To the above cited and other ends and with the foregoing and various other novel features and advantages and other objects of my invention as will become more readily apparent as the description proceeds, my invention consists in certain novel features of construction and in the combination and arrangement cf parts as will be hereinafter more particularly pointed out in the claim hereunto annexed and more fully described and referred to in connection with the accompanying drawings wherein:

Figs. 1 and 2 are plan and end elevational views of a spring mattress embodying the novel features of the invention.

Referring now to the drawings more in detail, the invention will be fully described.

The mattress 2 of the invention includes an outer envelope having secured together side, end and upper and lower walls t, Ii, 8 and Ill. An intermediate wall I2 extends between the side and end walls, between the upper and lower walls and is secured thereto.

The walls of the envelope may be made from various kinds of fabric such as is customarily used in bed-spring and mattress construction.

Transversely spaced rows of springs are provided between the lower and intermediate walls. The springs are spaced apart longitudinally in the rows thereof and are indicatedby I4 and I6.

The springs are secured tothe walls and relative to one another in the customary manner to prevent relative shifting thereof while permitting flexing thereof.

Between the upper wall 8 and intermediate wall the mattress part of the structure is filled with kapok or other suitable mattress making material.

In this way an upper mattress section is supported by a lower resilient spring section.

According to the invention the central most springs I6 are less yieldable or are harder than the springs I4 at the sides thereof.

This may be accomplished by springs l B which are tempered or are made from heavier wire or are more stili than the springs I4 so that they yield considerably less than do said springs I4.

For illustrative purposes one longitudinal row of springs I5 is shown but there may be plural rows if desired.

The arrangement and construction according to the invention is such that with two persons on the longitudinal side portions of the mattress their weights cause the springs I4 to yield appreciably more than do the springs I6.

Thus there is provided an elevated barrier extending longitudinally and centrally of the mattress which functions to separate and keep the persons on the mattress apart.

The relative yieldability of the springs I4 and I6 may be arranged as desired within the spirit and scope of the invention.

There may be a mattress section below the spring section as well as thereabove if desired.

When the mattress forms a made-up bed the same has the appearance of an ordinary bed there being nothing to detract from the normal appearance thereof.

The invention may be embodied in other specific forms without departing from the essential characteristics thereof, Hence, the present embodiments are therefore to be considered in all respects merely as being illustrative and not as being restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all modifications and variations as fall within the meaning and purview and range of equivalency of the appended claim are therefore intended to be embraced therein.

What it is desired to claim and secure .by Letters Patent of the United States is:

An elongated spring-mattress construction in combination, a casing having opposite and adjacent secured together longitudinal side and transverse end walls and upper and lower walls secured thereto, an intermediate wall secured to said Side and end walls cooperating therewith and with said side upper and lower walls to provide an upper mattress compartment and a lower spring compartment, mattress lling in said mattress compartment, la longitudinal central row of longitudinally spaced springs and longitudinal side rows of springs spaced transversely from and at the opposite sides of said central row including longitudinally spaced springs, upper and lower ends of said springs secured to said intermediate and lower Wall, said springs of said central row thereof being relatively less yieldable than the springs of the side rows thereof whereby f 4 with persons lying on opposite longitudinal sides of the mattress the springs of the side rows thereof yield to a greater extent than do the springs of the central row so that a central barrier is provided which extends longitudinally of the mattress and over the central row of springs.
